Seems similar to what Elastic did few years ago [1]. I kinda understand their motivation. It's not theirs originally, but they had antirez working on it for 5 years as their employee. They are making some contributions [2], I wish GH had a way to see such an insight by company affiliation. On the other hand, AWS and likes can easily fork pre-license-change version and spin it into its own product. However, I am fairly certain that AWS Elasticache is already such a thing – their own fork that diverged enough from the upstream and they are not eager to share.

So I view it as every major cloud provider with redis offering has its own fork. Except that Redis Labs also owns the original name. But it can go on as a stand alone project, like MariDB was spawn off after MySQL acquisition by Oracle.
